To all 'whom it may concern: i

13e it known that I, RALPH D. ALBEIGHT, a c1t1zen of the United States, residing at Reynoldsville, in the county of Jefferson and State of Pennsylvania, have invented certain new and useful Improvements in Water-Fixtures and Controlling Means Therefor, of which the .The primary object of this invention is to prevent Water'standing infxturesin exposedplaces' and freezing therein to the detrlment of the pipes. L

l The lnvention provides a novel construction whereby when the water is shut off in a hydrant or otherfixture, the latter will be. drained to a safe point below' the line of freezing with the result that the hydrant or p1 es are revented 'from bursting. 2 z

or a fu l description of -the invention and the merits thereof and also to acquire a knowledge of the details of constructlon and the means for effecting the result, reference 1s to be had to the following description and accom an gdrawings. l

While t e lnvention may be adapted to,

the structure and minor details without de parting rom the'spirit or essential features thereo still the preferred Jembodiment is shown in the accompanying drawings, in

which:

.Figure 1 is a detail view of a water fixture and controlling means therefor embodying. the invention. Fig. 2 is a sectional view'of ing the position of the latter ,when water is permitted'to flow throu h the-fixture and escape at the outlet. Fig 3 is a longitudinal sectlonal v iew through t e device. Fig. 4 is a 'transverse sectional view through one of barrel.

In the drawings, the'numeral lvindicates the service pipe provided withone or more outlets 2. l

3 indicates a barrel in which pistons 4 and chronousmovement. .The supply pipe is indicated at7. The'barrel 3 is provlded at its lower end with an opening 8 constituting a drain or waste for the escapeof water standing in the 'service' ipe after the su ply has been cut off. The arrel has an out et 9 and. an inlet 10, the latter being in communicaas well as the inlet 10 may consistv of through the outlet thereof.

pressure. lthe lower'portlon of the barrel may be discommuni-ation with the service pipe 1. The

piston 5 controls outlet 9, whereas the piston 4`p'revents the water assing'into the upper end of the barrel 3, hat part of the barrel embraced between the pistons 4 and 5 is at all times in communication with the supply and under pressure so that the instant the outlet9 isfuncovered, the water will pass from the barrel into the service ipe. It is to be understood that t e barrel i either located below frost .line or otherwise f protected to preventfreezing. The outlet 9 a sm' le op'emng or a series of openings, and int e latter construction, said openings extend around the-sides of the barrel. A casingll surroundsjthe ortion of the barrel having ythe series of" et openings 10 and a correspondin casing 12 surrounds the lower portlon ofl t e barrel having the series 'of outlet o enings 9. A space is providedbetween t e exterior' of the barrel and the inclos'ing portion of each casing, and the latterlis provided with a coupling end' 16 to which the pipes 1 and'71are connected in the accus' tomed Way. The pistons'4 and 5 each comprise a cup washer and plates, the cup washers being oppositely arran ed with their hollow sides facing so that t e water' confined `between them normally tends to expand the edge portions of the washers and force them in close contact with the inner wallsv ofthe barrel, thereby preventing any leak and. automatically compensating for wear.

The outlet controlling piston 5 normally, occupies a position above the outlet when the water is shut off, and when the water is,

turned on, thepiston 5 occu ies a position below the outlet, thereby a mitting 'of an uninterrupted flow from the sup ly pipe 7 into the barrel, thence outward t ough the outlet 9 and into the service pi e 1 and out he iston ma' bemoved by any means upon t e apphcatlon of force to the rod 6. A spring 13 normally resses the piston 5 upward so as to shut oil the supply of water to the service pipe when the r'od is relieved from stress or The' spring 13, whlle arranged 1n posed' -in any position so long as it serves to move the' piston 5 to cut off the sup ly from the outlet 9. The pistons 4 `and 5 t Within the barrel so as to reciprocate therein. Pressure ap lied to the piston 4 suliicient -to overcomet Ae resilience of the spring 13 and the soy vfriction between the pistons and the barrel,

will cause the pistons to move downward and uncover the outlet 9 and permit the water to flow from the barrel into the service pi e and out through the outlet thereof. As s own, a pipe 14 connects the upper portion of the barrel 3 with a pump 15 which may be of any type to admit of creating a pressure within t e upper portion of the barrel and upon the piston 4 to-eect movement thereof, and the piston 5 connectedtherewith. The pump 15 may be of an air compressing type to condense the air in the barrel above the piston 4 to cause movement thereof to effect uncovering of the outlet 9 when it is required to draw water from the outlet 2. When the pressure upon the piston 4 is relieved, the spring 13 regaining itself, returns the piston 5 to normal position and cuts off supply to the outlet 9, thereby ermitting the water in the service pipe 1 to gow back through the outlet 9 into the lower portion of the barrel and out through the waste or drain 8.` The pistons 4 and 5 are of like area. and since the water is confined between them, the force exerted upon one piston is counterbalanced by the force exerted upon the other piston and since the two pistons are connected by the rod 6 for simultaneous movement, pressure applied to the piston4 is transmitted to the piston 5 and moves the latter against the actionof the spring 13, the latter returning the pistons to normal position when the operating force or pressure is relieved.

Having thus described the invention, what is claimed as new is:

@oasis n a device of the character described, the combination of a barrel provided at one end thereof with a waste opening and communieating at the opposite end with an air supply pipe, the said arrel being provided wit i an upper annular row of openings and a lower annular row of openings, a pair of annular casings surroundin the barrel and communicating respective y with the upper set of openings and the lower set of openings, a service pipe communicating with one of the casings, a supply pipe communicating with the op osite casing, a pair of pistons mount ed within the cylinder and connected by a rod for simultaneous movement, the space between the pistons being greater than that between the two sets of openings, a siring inter osed between the end of the barrel provide( with the waste opening and one of the pistons and operating to normally move the pistons so that the space between the same is in communication with the inlet pipe while the service pipe is in communication with the waste opening, and an air pump cooperating with the air supply pipe at the op osite end of the barrel to force air into the liarrel and move the lpistons against the action of the
